virtual RefAST TreeParser::getAST ( )
pure virtual

Get the AST return value squirreled away in the parser.

virtual ASTFactory* TreeParser::getASTFactory ( ) const
inlinevirtual

Return pointer to ASTFactory.

virtual int TreeParser::getNumTokens ( ) const
pure virtual

Return the number of tokens defined.

virtual const char* TreeParser::getTokenName ( int  num) const
pure virtual

Get the name for token 'num'.

virtual const char* const* TreeParser::getTokenNames ( ) const
pure virtual

Return an array of getNumTokens() token names.

virtual void TreeParser::match ( RefAST  t,
const BitSet b 
)
inlinevirtual

Make sure current lookahead symbol matches the given set Throw an exception upon mismatch, which is caught by either the error handler or by a syntactic predicate.

virtual void TreeParser::setASTFactory ( ASTFactory factory)
inlinevirtual

Specify the AST factory to be used during tree building. (Compulsory) Setting the factory is compulsory (if you intend to modify the tree in the treeparser). The AST Factory is shared between parser (who builds the initial AST) and treeparser.

Parser::getASTFactory()
void TreeParser::traceIn ( const char *  rname,
RefAST  t 
)
virtual
void TreeParser::traceIndent ( )
virtual

These are used during when traceTreeParser commandline option is passed.

Procedure to write out an indent for traceIn and traceOut

void TreeParser::traceOut ( const char *  rname,
RefAST  t 
)
virtual

Member Data Documentation

ASTFactory* TreeParser::astFactory
protected

AST support code; parser and treeparser delegate to this object

RefAST TreeParser::ASTNULL
static

The AST Null object; the parsing cursor is set to this when it is found to be null. This way, we can test the token type of a node without having to have tests for 0 everywhere.

TreeParserSharedInputState TreeParser::inputState
protected

The input state of this tree parser.

int TreeParser::traceDepth
protected

Used to keep track of indent depth with -traceTreeParser
